Product Description
These ultra-thin N55 neodymium square block magnets deliver excellent magnetic performance in a miniature format. Made from premium rare earth alloy of neodymium, iron, and boron, each magnet provides 0.79 lb pull force while maintaining an extremely compact 1mm thickness.
Each block features protective nickel-copper-nickel coating to prevent corrosion and ensure durability. The thin, square design makes these magnets ideal for precision applications where space is limited, while the brittle ceramic-like construction requires gentle handling to prevent cracking or damage.
Important Safety Information
⚠️ WARNING: Handle with extreme caution - serious safety risks for children.
- CHOKING HAZARD: Keep away from children under 12 years old
- SWALLOWING DANGER: Can cause life-threatening internal injuries if swallowed
- Maintain minimum 6-inch distance from pacemakers and medical devices
- Prevent magnets from colliding forcefully to avoid dangerous shattering
- Keep away from electronic devices, credit cards, and magnetic storage media
- Use tweezers or magnetic pick-up tools for safe handling
- Store individually in non-magnetic containers or separated by thin spacers
